Moving up from Cardas Clear


I'm looking for opinions on where to go next from the Cardas Clear cable line. I've got a Meridian MS600/MD600 source (streaming audio), Simaudio P-8/W-8 amplification and Revel Studio 2 speakers. Cabling is all Cardas Clear, including power cords. I'm looking for something equally rich as the Cardas but with a tad more speed, dynamics and excitement.

Any suggestions?

The prices on the MG Signatures I saw were $6200 for the power cords (6 ft), $3500/$4250 for RCA/XLR interconnects, and $6000 for 8 foot biwire speaker cables. These were as of early 2012.

I got a chance to audition the prototype of the new Masterbuilt Ultra Extreme interconnects-- Delphi loaned me a prototype of the Ultra 2 meter XLR set at Axpona. The production version of these will be unchanged except possibly the external color. The projected price on the Ultras is $8k & $10k for one meter RCAs & XLRs with two meter XLRs at $12k.
Thanks. Signatures are pricey but not too out of whack as a step up from the Clears. Ultra Extremes are too expensive for me, though.
Camb, I've submitted a review of the Ultras (not yet approved & posted). I have to say that I wasn't prepared for the improvement the Ultras made and that was just with insterting just one pair of two meter XLRs. I sent them back in late April and I still greatly miss them. The review will go into more detail.

I like the Purist Dominus cables with Pranawire Cosmos speaker wire. I think they are a great match. It is what I use.
